CRAYON AND ERASER HOLDER FOR BLACKBOARDS.

SPECIFICATION forming part of Letters Patent No. 328,177, dated October 13, 1885. Application filed May 22, 1885. Serial No. 166,392. (Model) To all whom it may concern:

Be it known that I, IRVING WV. BARNHART, of Flint, in the county of Genesee and State of Michigan, have invented a new and Improved Grayon and Eraser Holder for Blackboards, of which the following is a full, clear, and exact description.

Blackboards and wall slates are usually provided at the bottom with a trough for receiving the crayons, erasers, &c.

The particles of chalkd'ust wiped off the blackboard accumulate in the said trough, and every time a piece of crayon or an eraser is placed into the trough the dust adheres to it, and when removed from the same the chalkdust is distributed and floats about the room, covering the clothes and furniture, and is inhaled by the pupils and teacher; besides, the crayons and erasers are at all times covered with chalk-dust and soil the hands and clothes of the pupils and teacher. The object of my invention is to avoid these difficulties.

My invention consists in the combination, with a trough, of a wire-netting or perforated piece held above the bottom of the trough, the crayons and erasers resting on said perforated piece.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a cross-sectional View of my improved crayon and eraser-holder. Fig. 2 is a plan view of the same.

The trough A at the base of the blackboard B has its bottom inclined from the rear to the front. To the top edge of the front part a piece, 0, of wire-netting or perforated metal is pivoted or hinged, the inner or rear edge of the piece 0 being bent downward at a right or other angle, for the purpose of stiffening the piece 0 and forming a support for its inner part.

A rod, D, is secured to the front edge of the piece 0, and from the ends of the said rod the pins E project into the eyes F, thus pivoti'rg the piece 0.

The piece 0 is usually from one-half to one inch above the bottom of the trough A, and the crayons G and eraser H are placed upon the netting, the rod D preventing them from rolling or sliding off.

They are held above the dust in the trough and always remain clean. The dust'wiped ofi" the blackboard can pass through the meshesf or apertures of the piece 0 into the trough. When the trough is to be cleaned, the piece 0 is swung down, as shown in dotted lines in Fig. l, and the dust, 820., is swept out ,of the trough.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination, with a blackboard-trough, of a piece of wire-netting or perforated material hinged to the front of the trough, and having its inner end bent down to form asupport for said netting, substantially as herein shown and described.

IRVING W. BARN HART.
